Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

What it costs to keep this loaded
Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00037 | $0.02372 |
| Opus 5 | $0.00018 | $0.01186 |
| Sonnet 5 | $0.00007 | $0.00474 |
| Haiku 4.5 | $0.00004 | $0.00237 |
Grade A, and why
intelligent-investor-graham scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 12d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Skill Purpose
Use this skill to apply Graham's value-investing discipline to practical investor decisions: distinguishing investment from speculation, screening defensive stocks, estimating margin of safety, responding to market swings, setting portfolio policy, evaluating funds or advisers, and searching for enterprising-investor bargains.
This is not a market-forecasting, momentum-trading, tax-planning, or personalized financial-advice skill. Its job is to force businesslike analysis, conservative arithmetic, and temperament discipline before any action is labeled an investment.
When to Use This Skill
Invoke this skill when the user asks questions such as:
- "Is this stock worth buying under Graham's rules?"
- "Is this an investment or speculation?"
- "Does this company pass the defensive investor checklist?"
- "What price gives enough margin of safety?"
- "The stock or market dropped. Should I sell?"
- "How should I split my portfolio between stocks and bonds?"
- "Should I buy this fund, adviser product, IPO, SPAC, or hot growth story?"
- "How would Graham look for bargain stocks?"

What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
